HTTORNEY Patented June 13, 1950 UNITED S TATES PAT ENT OFFICE WHEEL Charles S. Ash, Milford, Mich; Application August 2 1945, serial No. timid 1 (amine (:1. sonee) The present invhtion relates to "v emn wheas and more particularly' to a heavy duty type" of vehicle wheel "for c'arrying a plurality of road engaging elements. p

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned'by practice with the inventioh, the same being realized and attained by means of the instrumentalities and ombinations pointed out in the appended the inner or back side of the wheel looking outwardly;

Fig. 2 is a cross-sectional view taken along line 2-2 of Fig. 1;

Fig. 3 is a, fragmentary side elevational view of the wheel, shown in the two preceding figures taken from the outer or front side looking inwardly; and

Fig. 4 is an elevational view of a spoke end of the wheel shown in the preceding figures.

The present invention has for an object the provision of a strong and light weight vehicle wheel of a type adapted for heavy duty uses as, for instance, on trucks, busses, trailers and the like. The wheel of the present invention will be found to be of relatively simple design and. construction and thus economical to fabricate. Another object of the invention is the provision of an improved vehicle wheel adapted to demountably mount dual rims.

Referring now in detail to the illustrative embodiment of the invention shown by way of example in the accompanying drawings, the vehicle wheel of the present invention is a single integral member preferably of cast metal adapted to demountably mount a pair of side by side pneumatic tire rims. As best shown in Fig. 2 of the drawings, the casting is formed with an elongated substantially cylindrical hub portion l having internal finished bearing seats II and I2 to receive suitable roller bearings whereby the wheel may be mounted for free rotation on a vehicle axle end (not shown). The hub portion m ybe formed with "a flaiig l3 'at it s townien a swath hub cap maybe sfcurfd.

' Equau air umre rennau spaced about the Hub portion m, the when isfforrhe'dir'i pm outwa ii lv rad ans t ding stakes inc st generally by the numeral 15', each spfik being hollow and open becgprtewara the inner s'ideior the wheel, for gr ater ease in tasting the integral structure. As 'shdwn; each spak ash, ns, I p 1r or side webs is joined 'tdtiie hubl'li at their bases and exten ing (inwardly there: from. As best shown in Fig. 1, the of each spoke extend 'ofitwardly "s a 'll' a are an a w s; a a wh e1 iequidifsta betw enth'm. If desired, and as shown in the r ings, the websnfiay (ibnver slightly on eachjotherasthey progress outwardly.

At their bases where they join with hub por? tion H] the side webs I6 extend from front edges l1 substantially centrally of the length of the hub to back edges ['8 adjacent the inner end of the hub. Radially outwardly, the front edges ll curve axially outwardly to overhang the outer end of the hub l0 and terminate substantially at the end of the hub. The front walls of the spokes I6 comprise curved Webs 20 which are joined at their inner edges to hub l0 and along their curved lengths to the front edges ll of the side webs of their respective spokes.

At the top of each side web l6 of spokes l5 there is provided a flat edge or web 2| which extends from the rear to the front of the spoke ends. The edges 2| extend outwardly over their respective webs l6 and provide upper surfaces upon which to mount tire rims. At the front of the spokes I5 the fiat edges 2| of each spoke converge and join, as may be seen in Fig. 4 of the drawings. Immediately beneath the converging place of the edges 2|, the front web 23 of each spoke is thickened, as indicated at 22, and a threaded aperture is provided therethrough to receive 2. lug bolt 23. Each front web 20 is also provided with an axial extension 24 which joins the thickened portion 22 immediately above it, and the extensions 24 serve as seats for lugs 25 on lug bolts 23, providing means for holding the dual rims in place on the wheel.

At the rear edge of the outer ends of spokes l5 they are formed with circumferentially extending edges or webs 21 each of which merges with a respective fiat edge or web 2 I. The spoke end rear edges 21 are thickened and inclined to provide inclined seats 28 against which may seat the edge bead of a tire rim 29 of a, conventional type. Another tire rim 3!], which is preferably a duplicate of rim 29 but oppositely disposed, is mounted on the outer ends of spokes I5 on the surfaces provided by edges 2|, and a spacer ring 3| is positioned between the rims. The rims 29 and 30 are thus securely held in assembled relation on the wheel by means of lugs 25 and may be demounted when desired.

The spoke and rear edges 21 are supported and strengthened by webs 33 which extend radially inwardly from said edges and are formed integrally with respective back edge I8 of the spoke side webs Hi. The webs 33 extend radially inwardly to and merge with hub portion l0, being somewhat inwardly turned at their inner ends where they merge with the hub, as shown in Fig. 2. At places substantially radially outwardly of hub III the webs 33 of adjacent spokes l5 extend toward each other and join as indicated at 34 providing a web connection between the spokes. The connections 34 may be provided with seats 35 to receive a flange of a brake of any suitable and conventional type. Such a brake drum may be secured to the wheel by bolts received through apertures 36 provided in connections 34.

From the foregoing description it will be apparent that there is provided a. heavy duty type of vehicle wheel adapted to carry dual tire rims. The wheel is of light, spoked, construction but entirely sturdy and safe, and is simply and strongly formed of a single casting. The spokes are so formed that no core work is necessary in cast hub and a plurality of spokes cast integrally with said hub, each said spoke comprising a hollow body having a pair of spaced side webs and a front Web joining said side webs, an axially and circumferentially extending edge web along the upper edge of each said side web, said edge webs converging and joining at the outboard side of said spokes and having a radially outer, circumferentially extending surface at said convergence to seat a rim lug for an outboard rim, a thickened portion integral with said front web at the radially outer end thereof adjacent said convergence of said edge webs apertured to receive a lug bolt, said edge webs terminating at the inboard side of said wheel in thickened, inclined, circumferentially extending portions providing seats for an inboard rim, said edge webs, inclined portions thereof, and said side webs being spaced from each other providing spoke bodies open and entirely disconnected at the tops and inboard sides thereof from said hub to and through the periphery of the wheel.
